AI Model Mythos Threatens SEC Market Database, Financial Group Warns
The American Securities Association issued a stark warning on Thursday, stating that Anthropic PBC's newly developed artificial intelligence model, Mythos, presents a significant threat to traders and the broader financial system through its potential exploitation of a Securities and Exchange Commission database.
Consolidated Audit Trail Vulnerability
The financial-industry trade group specifically highlighted risks associated with the SEC's Consolidated Audit Trail, a controversial market-tracking database that has long faced opposition from industry stakeholders. According to the ASA, advanced AI tools like Mythos could enable bad actors to target this database for malicious purposes.
"The Consolidated Audit Trail was not designed to withstand the threat environment that Anthropic's Mythos has now made real," ASA President Chris Iacovella wrote in a letter to Treasury Secretary Scott Bessent, who also serves as chairman of the Financial Stability Oversight Council.
Potential Threats Amplified by AI
The ASA outlined several specific dangers that could emerge from AI exploitation of the CAT database:
- Mass identity theft of retail traders
- Exposure of individuals' private trading portfolios
- Amplification of insider trading threats
- Industrial-scale synthesis and misuse of decades of market data
Sultan Meghji, former chief innovation officer at the Federal Deposit Insurance Corporation and current CEO of AI company Frontier Foundry, emphasized that the concern extends beyond personal identity data. "Even de-identified CAT data is a strategic asset, and AI has changed the economics of exploiting it," Meghji explained.
Changing Threat Landscape
Meghji further noted that AI capabilities have dramatically altered the threat landscape. "What once took a nation-state team can now be accomplished with a laptop and open-source tools," he stated. "Mythos and systems like it push that further, enabling synthesis and misuse of decades of market data at industrial scale."
Regulatory Response and Industry Pressure
In response to these concerns, the ASA has called for immediate action from regulatory authorities. The group requested that Treasury Secretary Bessent suspend collection of retail traders' personal identity information in the CAT database and destroy personal trading data already collected.
The SEC has historically used CAT data for market surveillance and investigations into suspicious trading activities. However, the ASA argues that the database represents "a significant cybersecurity vulnerability waiting to be exploited."
This warning comes amid heightened regulatory attention to AI's financial implications. Last week, Bloomberg reported that Bessent and Federal Reserve Chair Jerome Powell met with leaders of Wall Street's top banks to discuss Mythos' capabilities and potential market impact.
Ongoing Legal and Regulatory Developments
The ASA's concerns build upon previous legal challenges to the CAT system. Last year, the ASA and Citadel Securities successfully challenged the database's funding structure, which had required exchanges to pay for its operation. Following this legal victory, the SEC has taken steps to reduce the CAT's operating costs.
Simultaneously with the ASA's warning letter, the SEC sought public input on potential changes to the CAT system. SEC Chairman Paul Atkins acknowledged the need for reform, stating, "The concept release seeks comment on foundational and existential aspects of the CAT." The White House has recently completed a review of agency measures that could lead to overhauling the scope of data collected.
A spokesperson for the Treasury Department did not immediately respond to requests for comment regarding the ASA's concerns about Mythos and the CAT database vulnerabilities.
